Vim li cas thiaj xaiv peb?
Kev paub nplua nuj
Peb cov kev paub dhau los ntawm kev ua haujlwm hauv kev lag luam hluav taws xob ntau tshaj 30 xyoo tso cai rau peb los tsim cov khoom siv hnub ci DC uas ua raws li cov qauv DC tshiab. Nrog rau qhov qub txeeg qub teg ntawm 30+ xyoo dhau los hauv kev tshawb fawb thiab tsim cov khoom siv tiv thaiv DC, peb tau mob siab rau mus rau EV charging field.
Kev lag luam dav
ZJBENY tau mob siab rau cov peev txheej hauv kev tshawb fawb txog EV cov khoom lag luam, ua tiav kev tsim lwm hom khoom, yog li tau txais kev lag luam thoob plaws ntiaj teb.
Cov khoom siv dav
ZJBENY muaj ntau yam khoom siv hnub ci PV tiv thaiv thiab EV chargers rau ntau lub hnub ci PV, roj teeb lub zog cia, thiab EV charging system. Peb Cov Khoom Tseem Ceeb: EV Charger, Cov Khoom Siv Hluav Taws Xob nrawm, Microinverter, PV Combiner Box, DC Isolator Hloov, DC Circuit Breaker, DC Fuse Holder, DC Contactor, AC Cheebtsam, thiab lwm yam.
Kev Pabcuam
Peb tus kheej ua tiav R&D, ntau lawm, kev lag luam, muag, thiab kev txhawb nqa txheej txheem. Peb txaus siab rau koj cov kev xav tau nrog peb lub warranty ntev, kev pab txhawb nqa, thiab lwm yam kev pabcuam ntxiv.
Lub DC Protector tau nruab rau ntawm lossis hauv cov khoom siv xws li DC servo mechanisms, hluav taws xob ntsuas hluav taws xob, kev tswj hwm kev ruaj ntseg, thiab lwm yam. Senses thaum muaj overvoltage tshwm sim thiab hloov los ntawm "qhib" mus rau lub virtual "luv" Circuit Court.
Qhov zoo ntawm DC Surge Protector
Thaum koj lub hnub ci PV system raug tiv thaiv kom zoo tiv thaiv qhov hluav taws xob, koj tuaj yeem cia siab tias yuav ua tau zoo tag nrho. Qhov no yog vim qhov kev pheej hmoo ntawm kev puas tsuaj rau cov khoom rhiab heev yog txo, tso cai rau lub cev ua haujlwm ntawm qib siab.
Muaj kev cuam tshuam tsawg kawg nkaus thiab cov khoom siv hluav taws xob zoo sib xws, uas ua rau kev ua haujlwm zoo dua qub thiab ROI siab dua. Qhov no yog ib qho tseem ceeb thaum nws los txog rau hnub ci kev ua liaj ua teb uas yuav tsum muaj cov khoom lag luam siab kom tau txais txiaj ntsig.
Hnub ci kev tiv thaiv hluav taws xob kuj tseem ceeb hauv cov tshuab hluav taws xob me me ib yam nkaus, uas yuav tsum muaj lub zog siv hluav taws xob thiab ua kom ntseeg tau.
Raws li peb tau hais ua ntej, qhov hluav taws xob hluav taws xob tuaj yeem ua rau puas lossis puas tsuaj rau cov khoom siv hluav taws xob hauv koj lub zog PV. Qhov no tsis yog tsuas yog kim ntawm kev kho thiab hloov pauv, tab sis kuj tuaj yeem ua rau muaj kev phom sij.
Ntxiv rau kev tiv thaiv cov khoom siv hnub ci xws li inverters thiab hnub ci vaj huam sib luag, hnub ci SPD cov cuab yeej tiv thaiv cov khoom siv hluav taws xob hauv lub zog xws li TVs, khoos phis tawj, khoom siv hauv tsev, thiab khoom siv hauv chaw ua haujlwm.
Los ntawm kev siv cov cuab yeej tiv thaiv kev tiv thaiv rau PV system tiv thaiv, koj tuaj yeem pab ua kom muaj kev nyab xeeb ntawm koj cov cuab yeej thiab zam kom tsis txhob muaj hluav taws xob hluav taws xob. Qhov no yog ib qho tseem ceeb hauv PV systems uas nyob rau hauv cov cheeb tsam uas muaj huab cua hnyav.
Lwm qhov txiaj ntsig SPD loj yog tias cov cuab yeej pab ua kom lub neej ntev ntawm koj cov khoom siv. Hnub ci vaj huam sib luag yog tsim los tiv thaiv qee theem ntawm qhov hluav taws xob, tab sis txhua yam dhau los ua rau muaj kev puas tsuaj.
Qhov tshwm sim tam sim ntawd hauv qhov hluav taws xob - lub npe hu ua qhov hluav taws xob tsis tu ncua - tuaj yeem los ntawm ntau qhov chaw, suav nrog xob laim tawm tsam, hluav taws xob hluav taws xob, thiab kev xaim tsis raug.
Thaum qhov ntawd tshwm sim, cov hluav taws xob tam sim no tuaj yeem dhau thiab ua rau cov khoom tsis zoo hauv koj lub hnub ci vaj huam sib luag. Qhov no tsis tsuas yog txo cov kev ua haujlwm ntawm koj lub cev tab sis kuj txo nws txoj sia. Los ntawm kev siv lub cuab yeej SPD, koj tuaj yeem tiv thaiv koj cov cuab yeej los ntawm kev hloov pauv thiab txuas ntxiv nws txoj sia.
Lwm qhov txiaj ntsig ntawm kev siv cov cuab yeej tiv thaiv surge yog kev txuag nyiaj. Thaum tus nqi pib ntawm kev nqis peev hauv SPDs yuav zoo li siab, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias lawv muaj kev txuag nyiaj mus sij hawm ntev. Qhov no yog vim tias lawv pab tiv thaiv kev puas tsuaj los ntawm kev hloov pauv, uas tuaj yeem kho tau kim.
Feem ntau, qhov kev puas tsuaj los ntawm ib qho kev tshwm sim ib ntus raug nqi ntau dua li SPD nws tus kheej.
Nyob rau lub sijhawm ntev, kev siv SPDs tuaj yeem txuag koj nyiaj. Qhov no yog vim tias lawv pab tiv thaiv kev puas tsuaj los ntawm kev hloov pauv, uas tuaj yeem kho tau kim.

Cov Txheej Txheem Txhim Kho
System Design Review:Ua ntej txhim kho DC SPD, tshuaj xyuas cov txheej txheem PV tsim thiab txheeb xyuas cov khoom tseem ceeb uas xav tau kev tiv thaiv, xws li: Inverters, tus nqi tswj thiab kev saib xyuas. Txiav txim siab qhov chaw tsim nyog rau nruab DC SPD raws li koj qhov kev teeb tsa.
Ua raws li cov qauv:Xyuas kom tseeb tias DC SPD koj xaiv ua raws li cov qauv thiab cov ntawv pov thawj rau hnub ci tiv thaiv hluav taws xob hauv cov ntawv thov photovoltaic, xws li: UL 1449, IEC 61643-31 lossis EN 50539-11. Ua raws li cov qauv no ua kom cov cuab yeej ua tau raws li kev nyab xeeb thiab kev ua haujlwm. Qhov tseeb grounding:
Kev cog qoob loo kom zoo yog qhov tseem ceeb rau kev siv lub hnub ci surge protector. Xyuas kom lub hnub ci array grounding system ua raws li cov cai hluav taws xob hauv zos thiab cov qauv kev lag luam. Tus neeg xyuas pib hauv av yuav tsum muaj qhov loj me, zoo txuas thiab xa mus rau qhov chaw hauv av electrode.
Kev teeb tsa ntawm DC SPD ntawm Main Service Nkag:Nruab ib hom 1 DC SPD ntawm lub qhov rooj ntawm lub tsev los tiv thaiv tag nrho cov hluav taws xob hluav taws xob, suav nrog lub hnub ci array. Txuas lub DC SPD nyob rau hauv parallel nrog lub input fais fab mov. Ua raws li cov chaw tsim khoom cov lus qhia rau kev xaim thiab kev sib txuas kom raug.
Txhim kho lub District DC SPD:Tshwj xeeb tshaj yog nyob rau hauv loj photovoltaic systems, Hom 2 DC SPDs yog ntsia rau hauv sub-distribution boards los yog collector thawv. Cov DC SPDs no muab kev tiv thaiv hauv zos rau circuits txuas nrog lub vaj huam sib luag. Txuas lub DC SPD nyob rau hauv parallel nyob rau hauv lub Circuit Court kom paub tseeb tias kev xaim thiab kev sib raug zoo nrog cov kev pabcuam tseem ceeb hauv DC SPD.
Ntaus-theem DC SPD Installation:Raws li qhov yuav tsum tau ua ntawm lub kaw lus thiab cov cuab yeej rhiab heev, koj yuav tsum xav txog kev txhim kho Hom 3 DC SPDs hauv cov txheej txheem tshwj xeeb xws li inverters thiab cov tswj hwm. Cov DC SPDs no muab cov txheej txheem tiv thaiv ntxiv ntawm qib ntaus ntawv. Ua raws li cov chaw tsim khoom cov lus qhia rau kev teeb tsa thiab kev sib txuas kom raug.
Bonding thiab Routing:Xyuas kom muaj kev sib txuas thiab xaim thoob plaws hauv PV system. Txuas tag nrho cov khoom hlau los tsim kom muaj kev sib koom ua ke kom txo qis qhov sib txawv. Siv cov kev coj ua kom zoo thiab qhov loj me ntawm cov xaim los tswj cov surge tam sim no thiab txo qis voltage te.
Tsis tu ncua thiab tshuaj xyuas:Tsis tu ncua xyuas thiab tswj cov teeb tsa DC SPD raws li cov chaw tsim khoom cov lus pom zoo. Qhov no suav nrog kev kuaj pom, kuaj, thiab hloov pauv yog tias tsim nyog. Kev saib xyuas tsis tu ncua pab ua kom muaj txiaj ntsig ntev ntawm koj lub tshuab photovoltaic tiv thaiv overvoltage.
Peb pom zoo kom koj sab laj nrog lub hnub ci teeb pom kev zoo lossis tus kws tshaj lij hluav taws xob rau kev teeb tsa tshwj xeeb rau koj lub hnub ci thiab cov kev cai hauv zos.
